[CC'ing to python-dev] Confirmed:
[amk@mira Python-2.0]$ ./python Lib/test/pystone.py
Pystone(1.1) time for 10000 passes = 3.14
This machine benchmarks at 3184.71 pystones/second
[amk@mira Python-2.0]$ python2.1 Lib/test/pystone.py
Pystone(1.1) time for 10000 passes = 3.81
This machine benchmarks at 2624.67 pystones/second
The ceval.c changes seem a likely candidate to have caused this.
Anyone want to run Marc-Andre's microbenchmarks and see how the
numbers have changed?
